To all whom t't' mc'y concern:

Be it known that I, ELIA S B. A DERS N, citizen of the United States,residing at'Rock Falls, in the county of Whiteside andS tate ofIllinois, have invented certain new and useful Improvements inSpring-Theels, of which. the following is a specification.

The presentinvention'provides a wheel of novel formation having ayicldable and slidable rim, and cushioning devices between the rim andhub to absorb shock and vibration so a's'to secure ease and comfort tothe passenger, as well as prevent injury to thevehic'le or conveyancemounted upon whels'em bod yIn-g-the mventlon.

Fora full understandin .of the invention and the merits thereof an alsoto acquire 'a knowledge of the details of construction and means foreffecting the result, referenceis to be had to the following descriptionand accom anying drawings.

Wlnl' e the-invention may be adapted to different forms and conditionsby changes in the structure-and minor details without departing from thespirit or essential features thereo still the preferred embodiment isshown in the accompanying drawings in which- Figure 1 isa sideview of avehicle wheel embodynr the invention, 'arts being broken away to s owmore clear y the relative arrangement of the elements and details ofconstruction. Fi 2 is a transverse section on'the line :v.r 0 Fig. 1..

Corresponding and like parts are referred to m the following descriptionand indicated in all the views of the drawings by the same referencecharacters. The wheel comprises a hub and'rim between which. thecushioning devices are located, said parts being relatively movable andthe cushioning devices being of such re" sistance as to insure stabilityand yet neutralize shock and vibration and prevent transference of thesame tothe body of the ve hole. The hub 1 has a reduced central flange2, the-outer edges of which are flared as at 4. Bolted to the sides ofthe hub 1 are s1de plates 3 which are offset at 5, thereby increaslngthe sna'ceubetween their outer edges to accommodate the cushioningdevices. Pins 6 connect the plates 3 at intervals near their outer edgesand brace the sameagainst both inward or outward movement. The runcomprises a ring 8 secured between the tions of the plates 7 and passthrough olpeuings 12 formed in thefiange 2 -and si e p' sites the ringis the tire 9. I Bolts or oth'erfasten 3 at regular intervals. The sideplates? fit close against the outer-portions of the side .la'tes 3,sufficient surface being providedto lir'ace the wheel laterally againsttransverse stress. The tire '9 is secured between the outer ortions pfthe plates 7, said outer pertions prevent the posslple displacementthereof,

said tire being seatedfupon the ring'8 and supported thereby. The boltsor fastenings 11, In addition to connecting the innerpo'rtions of theplates 7, limit the movement of the rim, the size of the openings 12detereing formed with inner extensions 13 to-engage with op ositesides'o'f'the tlre and mining the amplitude of movement in anydirection. i p l The cushioning devices are interposed between the ring8 and the periphery of the flange 2 and consistsof'springs', as shown inFigs. 1 land 2; The springs 14 may be of any slze, material,construction and tension and are confined between; the 'fla'nge 2 andheads 16-. Guide and retaining means cooperate with the springs 14 toconfine the same in place and con'sistfi'gf a pin 15 and tube 16, thepin 15 being sedated at its inner end to theflange 2, and tube 16 havinga head or flange 16 at its outer end and seated against the inner sideof the ring 8. The springs 14 are mounted upon ulde means and aresupported thereby. he and tube 16 are of such relative lengt as" totelescope and admit of the rim' movin radially under vibration to absorbthe shoe produced thereby 'The outer headed ends of the tube 16, areseated against the inner side of the rim 8, but are not rigidly connected thereto. This construction is essential to permit slidablemovement between the rim and the heads 16 which are out of direct lineof the load pressure.

.In operation, when a load is applied, the cushioning devices in linewith the pressure will compress. That is, the vertically disposed sprins will be com ressed and the pins and tu es 15- and 16 t ereof willtelescope.

compressed to the same degree as those in The cushioning devices out ofaline ment with the Ioadpressure cannot become-- alme'mentwith the loadowing to their very- .absorb the shock. It will also be observed thatall the heads 1b are in direct contact with the inner surface of thering8, which tends to equalize the strain on the" parts.

Havin thus described the invention, what is o aimed as new is:

1. In a wheel, the combination of a hub provided with a flange formedwith openings, and having. its opposite outer edges enlarged, platessecured to the sides of the flanges, and formed with openingscorresponding with the openings in the flange and extended'beyond theedge of the flan c, said plate being shaped to correspond to t eenlarged edges of the hub,; a rim, pins secured to the hub flange, tubesfitting over the pins, and having their outer ends at all times bearingon the inner surface of the rim, flanges on, the tubes, springs mountedover the tubes and pins and bearing on the tube flanges and theperiphery of the hub flange, side plates extended inwardly from therimand overlapping-the plates of the hub, and pins connecting the innerportions of the side plates and passing through the opposite sides of oenings in the hub flange and the hub p ates to limit the movement of therim, the openings in the hub and plates being, of larger diameter thanthe diameter of the pins.

2. A wheel as specified comprising a hub,

a flan e intermediately formed on said: hub,

said" ange being flared outwardly at its outer edge, plates positionedagainst the said flange, said plates having a plurality ofequi-distantly spaced apertures, concentrically disposed therein inregistered relation, said plates being flared outwardly to-register withthe flared edge of said flange, a second pair of plates engaged secondplates being cut away centrally, a

. plurality ofbolts transversely disposed between said second pair ofplates and engaged loosely through the apertures formed in said againstthe outer faces of said plates, said first plates, studs radiallyextended in equidistant relation about the periphery of said flange,cylinders loosely disposed over said studs for slidable engagementthereon, a ring carried upon the outer extremities of said cylinders, atire mounted. upon said ring and between the outer edges of said secondplates and springs disposed about said cylinders and said studs betweensaid flange and said ring for forming a resilient connection Intestimony whereof I afiix my signature in presence of two witnesses.
